To all whom 'it may concern:

lie it known that I, Josinir Kinnuan, a

citizen ol' the llnited States, and residing at Los Angeles, in the county of Los Angeles, State ot` California, have 'invented oertain new and useful Improvements in Composition for ltailway-l`ies, SLC.; and l do declare the following' to he a full, clear, and exactY description ot' the invention. such as will enable others skilled -in the art to which it pertains to make and use the same. My invention relates to improvements in composition more especially for use in making railway ties, fence posts, gates, piers for foundations, etc.

It has for its object to provide a` composition for the above purposes which is water, fire, rust, decay and vermin prooil and indestructible, and which Will not expand or contract, and which by its great tensile strength will stand any strain that it is subp'ected to withoutail'ecting it.

Referring to the drawing:Mifiguro 1, is a, -top plan View of two tiesl with the railsI thereon. Fig. 2, across section on line X-X ofl one ot' the ties, shown in Fig. l.

In the drawings in which like numerals ot' reference denote like parts throughout the several views, l represents the railway ties and 2 the rails secured thereto.

The composition for making the railway ties, fence posts, etc., comprises the following ingredients z--Lime rock, about per about 20 per cent. 5'

silicagrit, fro1n.about 5 to 15 per cent.; pulp tiber, about 12 per cent.; asphaltum composition, or tar composition, about 8 per cent. The exact proportions are not given. as they are -not fixed, but have to be varied according to the quality of the-materials which vary in different localities. The asphaltum composition comprises about per cent. asphaltum and l() per cent. of sult'ur. The tar composition comprises about 90 er cent. of tar and 10 per cent. ofsulfur. ne of the above named. compositions, but not both, is used at. a time.

lnstead of using the aspbaltum composi- 't-ion or the tar composition as above de scribed, asphaltum or tar may be used when found desirable.

1. A composition-for use'in making railroad cross-ties comprising, lime,1'oclr, kaolin, silica grit, pulp fiber, asphaltum or tar compositions, substantially as described.

2. A. composition for use in making railway ties comprising lime rock, kaolin, (common), silica grit, pulp ber, asphaltum or tar, substantially as described,
